… This anisotropy, first of all, gives rise to the nonlinear transverse cascade, and one of the
main goals of the present paper is to vividly demonstrate its importance in forming the
overall dynamical picture of net vertical field MRI turbulence. … In view of the above, in this
work, we focus on the dynamics and balances in MRI turbulence with a net vertical field. We
adopt the local shearing box model of the disk with constant vertical thermal stratification.
The analysis is performed in three-dimensional (3D) Fourier space in full, ie, without doing …
Abstract
We studied dynamical balances in magnetorotational instability (MRI) turbulence with a net vertical field in the shearing box model of disks. Analyzing the turbulence dynamics in Fourier (
